The victim, a 29-year-old man, said he was escorting an intoxicated man and woman from Downtown Crossing Station at 3:30 a.m. when the man "sucker punched" him, according to a police report.

The man, identified as Robert Snyder, 45, of Roxbury, allegedly put the victim in a bear hug as the woman, identified as Shayla Witts, 28, started punching him in the head and ripping his hair out, police said.

The victim, who was bleeding and had several bruises to his face, was taken to Tufts Medical Center.

Police said there was a blood stain about 30 feet long on the sidewalk outside the entrance to the station.

As Snyder and Witts were being questioned, police said they used racial slurs when talking about the victim and the responding officers.

Witts said “her man” had “done 17 years in prison, and doesn't take (expletive)" from people she described by using the n-word, police said.

In addition to assault charges, the pair is facing civil rights violations.

They are scheduled to be arraigned in Boston Municipal Court on Monday.
